用于点燃以气体运行的内燃机的气体混合物的点火装置
摘要：
本发明涉及用于点燃以气体运行的内燃机的气体混合物的点火装置，其用于点燃在借助气体运行的内燃机的主燃烧室(11)中的气体混合物，其中，点火装置(1)具有壳体(2)，其带有构造成预燃室(4)的内部凹部(3)与提供点火火花的、用于点燃在预燃室(4)中的气体混合物的装置(6)，并且壳体(2)具有用于点火火焰从预燃室(4)穿透到主燃烧室(11)中的溢流孔(10)以用于点燃在主燃烧室(11)中的气体混合物，并且内部凹部(3)具有朝溢流孔(10)的方向上在截面方面加宽的区域(8)。
摘要（英）：

PROBLEM TO BE SOLVED: To improve an ignition device for removing disadvantages.SOLUTION: An ignition device (1) is proposed for igniting a gaseous mixture in a main combustion chamber (11) of an internal combustion engine driven by using gas. The ignition device (1) comprises a housing (2) including an internal recess (3) which forms a pre-combustion chamber (4) and includes a device (6) for providing ignition sparks for igniting the gaseous mixture in the pre-combustion chamber (4). The housing (2) includes an overflow opening (10) for passing an ignition torch from the pre-combustion chamber (4) into the main combustion chamber (11) in order to ignite the gaseous mixture in the main combustion chamber (11). The internal recess (3) includes an area (8) which is enlarged towards the overflow opening (10) with respect to a cross section.
